There are a lot of similarities between the three shows. Especially the characters

Reef- Jonsey and Geoff
Fin- Looks like Caitlyn and is like Bridgette
Broseph- Owen and looks liek Wyatt
Emma- Is like Gwen (nice) and looks like Bridgette
Lo- Is like Lindsa and Heather
Ripper- Like Geoff tooo and acts like Duncan kinda

Like TDI they are on a ビーチ and like 6teen they have a wide range of charcters.

Three showws are all awesome and hope we see more!

They all are funny and act like they are family (most). They all have enemies and all have crushes. FOR NOW!
